viii) Post-intervention (end of week 8) follow-up and management By the end of week 8, the subject will be completely off the study medication. Since study medications cannot be continued following completion of the protocol, this visit will, in part, be devoted to establishing ongoing care and treatment. All subjects will be offered ongoing care, treatment, and follow up with Dr Singer at Johns Hopkins. If the subject already has a treating physician, Dr Singer will be available to provide consultative services. Neither the Investigators nor subjects will receive information about the experimental drug assignment until the entire study has been completed.
